Error: godot could not parse global class

What's Causing This Error

The error "godot could not parse global class" typically occurs when Godot Engine encounters a problem with parsing script files that are set to be global classes (singleton). This can happen due to several reasons:

• Syntax Error: A common cause is a syntax error in the script that has been marked as a global class.
• Incorrect File Path: If the path specified in project.godot under [global_classes] does not match the actual location of the script, Godot will fail to parse the global class.
• Improper Class Name: The class name might not match the file name or the class name inside the script, which is required for global classes.
• GDScript Version Mismatch: Occasionally, if you've upgraded your project from an older version of Godot, there might be deprecated syntax or functions that are no longer supported or have different usage guidelines.

Solution - Here's How To Resolve It

To resolve the "godot could not parse global class" error, follow these steps:

1. Check Syntax: Open the reported script and carefully check for any syntax errors. Make sure that all functions, variables, and blocks are correctly defined.

2. Validate Paths: Go to the project.godot file and ensure that the paths under [global_classes] are correct and that they point to the actual location of your script files.

3. Match Class Names: Ensure that the class name within the script matches the script’s file name and update it accordingly if needed. If you're using inner classes, make sure they are also named properly.

4. Update Deprecated Code: If the error occurred after updating Godot Engine, review the changelog for the version you're using. Replace any deprecated syntax or functions with their current counterparts.

5. Re-add Global Classes: Remove the problematic global class entries from the project.godot file, and then re-add them using the Godot editor through Project Settings -> AutoLoad tab to ensure that the paths and names are set correctly.

By following these steps, you should be able to resolve the "godot could not parse global class" error and get your Godot project running smoothly again.
